The Zoom ADSL 2+ Microfilter 98027 must be plugged into all active telephone sockets on your ADSL line which are used for plugging in telephony equipment. You'll need one Zoom ADSL 2+ Microfilter 98027 per socket you wish to connect your telephony devices to. This easy-to-install device ensures clean separation of data signals from voice signals. Without microfilters, you may experience noise on the line when you make or receive a telephone call, or may experience connection problems with your ADSL Broadband service, including low speeds and disconnections. Each Zoom ADSL 2+ Microfilter 98027 has a socket for a standard telephone plug (like those on the end of equipment such as telephones and fax machines) and a socket for a broadband (ADSL) modem. A maximum of four ADSL can be used on an ADSL line. This is the recommended maximum number of items of telephony equipment you can plug into a standard voice line.
